Release nine of the Whitehead Institute/MIT Genome Center Genetic Map
of the Mouse is now available.  This map consists of randomly-chosen
simple sequence length polymorphisms (microsatellites) that can be
analyzed using the polymerase chain reaction, as described in Dietrich,
W., et. al., Genetics 131:423-447 (1992), and most recently in Dietrich,
W.F. et al., Nature Genetics 7:220-245 (1994)

Currently the released map contains 5752 markers.  The markers fall into
20 linkage groups spanning approximately 1400 cM with an average spacing
of approximately 0.25 cM.

This data can be obtained in three different ways:

1.  (Preferred method) Via a "World-Wide Web" browser.  Point your WWW
client (e.g., NCSA Mosaic, Netscape) at "http://www-genome.wi.mit.edu/".

2.  Via internet e-mail using a database e-mail server. Using this
service you can obtain locus and assay names of mapped SSLPs, the
forward and reverse primer sequences, the genotypes of the loci on the
mapping cross, the sizes of the PCR products on selected standard inbred
strains, and other useful information.  The database can be queried for
markers meeting a number of different criteria.  For example, you can
ask for markers by name, by chromosome, or by position on the map.  You
can even request a list of markers that are polymorphic between two
mouse strains.

3.  Via anonymous ftp to genome.wi.mit.edu.  Log in as "anonymous" and
use your e-mail address as password.  The release can be found in the
directory /distribution/mouse_sslp_release/jan95/.  The file "README"
describes the file formats and gives other information about the map.

To obtain copies of the most current e-mail query forms, send a message
to "genome_database at genome.wi.mit.edu" with either a subject line or
body text of "help". You will receive instructions and a query form by
return mail.  Just fill out the form, send it to
"genome_database at genome.wi.mit.edu", and the answer to your query will
be mailed back automatically.

This project is an ongoing one.  As new markers are added to the map
they will be released on a quarterly basis.

These data releases do not constitute scientific publication of CGR's
work, but rather provides scientists with a regular look into our lab
notebooks.  For projects aimed at the analysis of particular genes or
subchromosomal regions, the Whitehead/MIT CGR grants permission to use
our data without the need for a formal collaboration, subject only to
appropriate acknowledgment.  For projects aimed at large-scale mapping
of entire chromosomes or entire genomes, use of the data and markers
should be on a collaborative basis.  Please see the aforementioned
README file or contact CGR directly.
